Replacement skates for a scooter

ABSTRACT

A set of replacement skates for a scooter. The replacement skates are designed such that each replacement skate can replace a wheel on the scooter. A kit may also be provided with a front end replacement skate and a rear end replacement skate. Both replacement skates have attachment means for fastening the skates to the scooter using the same pins and fasteners used to attach the wheels.

FIELD OF INVENTION

[0001] The present invention relates to replacement skates for a scooter for use in the winter season. More particularly, this invention relates to two replacement skates that have been adapted to replace the two wheels on the scooter using the same screws which have attached the wheels to the scooter.

BACKGROUND TO THE INVENTION

[0002] The scooter is either considered an amusing toy for children or a transportation means for adults. The dictionary definition for a scooter is that of a child's toy consisting of a footboard mounted on two wheels with a long steering handle, propelled by resting one foot on the footboard and pushing the other against the ground. Unfortunately, the scooter has certain deficiencies in that it may only be used during the summer months or in climates where winter, ice, and snow do not a pose concern. For those who inhabit cooler climates, the winter, fall, and possibly spring months, provide snow on the gravel roads and ice covering most bodies of water. In such snowy and icy conditions, the scooter cannot be driven through the snow since the wheels will get stuck in the snow. Similarly, the scooter may actually be dangerous on ice, as there is a lack of sufficient friction between the ice and the wheels. This lack of friction prevents the wheels from gripping the icy surface.

[0003] The present invention seeks to overcome the above shortcomings by providing a set of replacement skates for the wheels on the scooter so that the scooter can be utilized in the winter months.

SUMMARY OF THE INVENTION

[0004] The present invention seeks to provide a set of replacement skates for a scooter. The replacement skates are designed such that each replacement skate can replace a wheel on the scooter. A kit may also be provided with a front end replacement skate and a rear end replacement skate. Both replacement skates have attachment means for fastening the skates to the scooter using the same pins and fasteners used to attach the wheels.

DETAILED DESCRIPTION

[0028]FIG. 1 illustrates a scooter 5 according to the prior art. The scooter 5 consists of a shaft 10 connected to a footboard 20. The shaft is supported by a radial bearing 30 which allows the shaft 10 to rotate on its longitudinal axis. The handlebars 40, fixed onto the upper end of the shaft 10, permit the user to rotate the shaft 10 by turning the handlebars right or left. The shaft 10 extends through the lower end of the radial bearing 30 and is attached at the lower end to a wheel bracket 50. This wheel bracket 50 holds the front wheel 60 in place using a pin with two fasteners one on either side of the pin 55. A connecting piece 70 is attached between the radial bearing 30 and the footboard 20. The connecting piece 70 may be of various shapes. In FIG. 1 it is shown as a flat piece with angled ends. The angled ends permit the connecting piece 70 to be attached to both the radial bearing 30 and the footboard 20. The shaft 10 and the footboard 20 are shown as being approximately at right angles to each other.

[0029] The connecting piece 70 has a slot piece 80 with two slots 90A, 90B which enable the user to fold the scooter 5 by rotating the footboard 20 into the shaft 10. The slot piece 80 is attached to the footboard 20 in order to fold in the scooter. There are two pins 100A and 100B, attached to the connecting piece 70, which travel through the slots 90A and 90B respectively. Both slots 90A and 90B are arc-shaped. When the two pins have traveled to the opposite ends of the two slots 90A and 90B then the scooter 5 is in a folded state. The scooter 5 shown in FIG. 1 is in a functional state, as the rear wheel 110 is level with the front wheel 60 and the shaft 10 and footboard 20 are at approximately a 90 degree angle to one another. Along the footboard 20, opposite the connecting piece 70, is attached a rear wheel 110 using a conventional wheel bracket 120 with a pin holding the rear wheel 110 to the bracket 120. Between the bracket 120 and the connecting piece 70 and adjacent the bracket 120 is an attachment means 130, such as a fastener, for maintaining a mud guard 140 above the rear wheel 110. On certain scooters, the mud guard 140 is a rear brake whereby the user presses down on the brake to provide friction against the rear wheel. This effectively slows down the scooter and eventually stops the scooter.

[0030]FIG. 2 is an illustration of replacement skates shown installed on the conventional scooter 5 of FIG. 1. The difference between the scooter 5 of FIG. 1 and the scooter 150 of FIG. 2 is that the wheels 60, 120 have been replaced with replacement skates 160, 170. Apart from the replacement skates, the scooter 150 of FIG. 2 is essentially the same as the scooter 5 of FIG. 1. It should be mentioned that both replacement skates 160, 170 are identical to each other. In fact, any of the two replacement skates 160, 170 can be installed in either the front end and the rear end of the scooter 150. It will be explained in further detail below that the orientation of the replacement skates may differ according to which end of the scooter 150 they are to be attached.

[0031]FIG. 3a illustrates the side view of the replacement skate 160 attached at the front end of the scooter 150. As can be seen, the replacement skate 160 is attached to the wheel bracket 180 with a pin 185 and two fasteners 190. The pin and fastener combination 195 is the same pin and fastener combination 55 of FIG. 1. The pin 185 may be threaded at both ends such that nuts are used for engagement with the threaded ends of the pin 185. The replacement skate 160 has a blade support structure 200. The blade support structure 200 is attached to the wheel bracket 180 by way of the pin and fastener combination 195. The pin 185 and two fasteners 190 are attached at a centrally located attachment opening in the blade support structure 200. The attachment opening (shown in FIG. 5) in the blade support structure 200 is suitably sized such that the pin 185 fits snugly in the opening. The two fasteners 190 secure the support structure 200 to the wheel bracket 180. The blade support structure 200 is attached to a skate blade 210 the same way any blade would be attached to a conventional ice skate. It can be seen from FIG. 3a that the front end 210 of the blade support structure 200 is taller than the rear end 220 of the blade support structure 200. According to this embodiment of the present invention, there are two support structure openings 240, 250 in the blade support structure 200. The two openings 240, 250 are not essential parts of the blade support structure 200. Rather, the two openings decrease the weight of the replacement skate 160 so that children may easily handle the replacement skates.

[0032]FIG. 3b illustrates a front view of the replacement skate as installed on a scooter. The wheel bracket 180 is attached to the support structure 210 of the front end replacement skate 160 by means of the pin 260 and the fastener 270 in combination. The blade support structure 260 supports the blade 210. The footboard 280 is shown extending on either side of the blade support structure 210.

[0033]FIG. 4 illustrates a side view of the replacement skate 170 at the rear end of the scooter 150. The replacement skate 170 is identical to the replacement skate 160 described in FIG. 3a and FIG. 3b. However, the orientation of the replacement skate 170 is opposite to that of the replacement skate 160. The support structure of the replacement skate 170 is to the rear of the scooter. The orientation of the replacement skate 170 is due to mainly to the constraints of the footboard 300. The large cross-sectional area 310 of the support structure 320 does not permit the replacement skate 170 to be oriented the same way the front replacement skate is oriented. The opposite orientation would prevent the blade 330 from being level with the footboard 300. The replacement skate is attached to the footboard by means of the pin (not shown) and the two fasteners 340 in combination. Again, the opening of the replacement skate 170 should be sized such that the pin fits snugly in the opening.

[0034]FIG. 5 illustrates the side view of a replacement skate 350 as provided in a kit of replacement skates for a scooter. Although the replacement skates are identical this need not be the case. It is conceivable that such a kit would provide a front end replacement skate that has a different support structure and a differently sized and shaped to that blade of the rear end replacement skate. The replacement skate 350 has an opening 360 centrally located in the support structure 370. The blade 380 is typically made of stainless steel but may also be made of any suitable material.

[0035] Typically the skates will be made available in pairs as a set for replacing both wheels on the scooter. Furthermore, the pins and the fasteners may not be required in the kit as the opening in the support structure is sized to fit snugly over the pin used for the wheels on the conventional scooter.

[0036] In another embodiment, it is possible that the replacement skates may be designed for any multi-wheeled device or for example, replace the wheels on children's tricycle.
